Superpower story in which the writing-person is too stressed to think up a synopsis at this exact moment in time. Yet, here is one anyways:

Blake is on the run from his past. His power allows him to mirror the visage - and thus, the lives - of the recently deceased. When his most recent identity decays, Blake's attempt at coming up with anewbody spirals, cumulating in the painful takeover of a hero's corpse found on the city's river's edge.

Now, recovered by police and the dead hero's team, he must act the part.
